As someone else said, it is only stupid to not ask your question.  Basically
unless you do something strange, the standard behavior of windows such as
moving them and sizing them and redrawing them is handled by PM.  You
have options to override them but people usually only do this to support
something rather different.

Your question suggests to me that you are probably not familiar with
how PM programming works.  You probably could use a book on the subject
to learn the basics.  Things like what makes up a minimum PM program?
The best book I've seen on the subject is pretty old, Charles Petzold's
Programmiing the Presentation Manager.  It covers only PM at level 1.1.
However what it covers is still real important and by taking you through
a series of programs to learn how, you build up an understanding of
the approach.  This book does it better, in my opinion, than any other
I've reviewed.  Others will probably disagree.  However, the problem with
Petzold's book is that it is VERY hard to find.  It is published by
Microsoft Press(!!!!).  It appears that they made it 'out-of-print'
even when there was some demand for it.  Occaisionally one sees a copy
especially in a used book store.  One might also be able to borrow a copy.

Good luck.  Don't be afraid to ask questions.  Remember that the question
you ask and get answered may help many other people as well.
